The bystanders, a doctor and off-duty paramedic, used CPR and an automatic external defibrillator taken from the school to treat the man, who had collapsed while playing the game.

The bystanders were able to deliver one life-saving shock to bring the man, who was unconscious and not breathing, back into a viable heart rhythm, said Clackamas Fire District 1 spokesman Brandon Paxton.

Fire crews arrived around 1 p.m. at the school, 11999 S.E. Fuller Road, east of Milwaukie, administering advanced life support measures to stabilize the man before he was transported to Kaiser Sunnyside Medical Center. He is in stable condition at the center.
